    摘要： The present invention relates to a fuel cell separator and a method of producing the fuel cell separator. A first separator and a second separator are provided as the fuel cell separators. Firstly, the first separator and the second separator are heated. Thus, an Fe rich layer is formed in a surface layer of each of the first separator and the second separator, and a Cr rich layer where a proportion of Cr is 60% or more is formed in an inner portion of each of the first separator and the second separator. Then, an electrolytic treatment is applied to each of the first separator and the second separator to remove the Fe rich layer. By the removal, the Cr rich layer is exposed to the outside on the outermost surface layer of each of the first separator and the second separator.

    摘要： A quality evaluating apparatus has an inspection table for placing a first or second metal separator, and a light-permeable plate for applying a predetermined pressure to a ridge of the first or second metal separator to deform the ridge and allowing a deformed state of the ridge to be inspected through the light-permeable plate while the predetermined pressure is being applied to the ridge. The quality evaluating apparatus also has an image capturing mechanism for capturing an image of the deformed state of the elastic member through the light-permeable plate, and a comparing mechanism for comparing the captured image with a preset image to evaluate the quality of the ridge.

    摘要： A stacked body is formed by stacking a plurality of power generation cells in a stacking direction. End power generation cells are provided at opposite ends of the stacked body in the stacking direction. Each of the power generation cells includes a membrane electrode assembly and first and second metal separators sandwiching the membrane electrode assembly therebetween. The end power generation cells include first outer separators and second outer separators. The first outer separators are more highly hydrophilic in comparison with the first and second metal separators of the power generation cells.
